Abstract
A seating device (1) with a reclining function comprising a back frame (4) which provides a significant reduction in the complexity of the system, at the same time as it gives the user increased comfort both in an upright (sitting) position and in a reclining position. The back frame (4) comprises in particular two types of resilient elements (7, 8) and rotatable fasteners (6) which provide adaptive support to the lumbar spine in both a sitting and reclining position.
Claims7
A seating device with reclining function comprising a seat, a backrest element and a rotatable hinge element which connects the seat to the backrest element, wherein the backrest element comprises padding and a back frame including at least one first resilient element arranged between one or more second resilient elements, wherein each resilient element is bonded to the back frame via fasteners at each end thereof, the at least one first resilient element being curved convexly towards a back of a user when the seating device is in the sitting position, and the at least one first resilient element being arranged to assume a curved concave shape against the user's back when the seating device is in a reclined/loaded position, and wherein the at least one first resilient element is longer than the one or more second resilient elements, and the one or more second resilient elements are stiffer and less resilient than the at least one first resilient element.
A back frame for use in a sitting device with reclining function, wherein the back frame comprises at least one first resilient element arranged between one or more second resilient elements, wherein each resilient element is bonded to the back frame via fasteners at each end thereof, the at least one first resilient element being curved convexly towards a back of a user when the seating device is in the sitting position, and wherein the at least one first resilient element is arranged so that it assumes a curved concave shape against the user's back when the seating device is in the reclined/loaded position, and wherein the at least one first resilient element is longer than the one or more second resilient elements, and the one or more second resilient elements are stiffer and less resilient than the at least one first resilient element.
